Nitrogen removal from low COD/TN ratio manure-free piggery wastewater within an upflow microaerobic sludge reactor

• An innovative upflow microaerobic sludge reactor was constructed. • Removing NH4 + and TN from manure-free piggery wastewater with COD/TN ratio 0.84. • The average TN load removal reached 0.94kg/(m3 d) at NLR of 1.10kg/(m3 d). • Anammox was the main pathway for NH4 +-N and TN removal in the reacto...
